How to load FX2 firmware (std.ihx) in Windows?

Hi,As suggested by you, I am now using the usrp_standard.h to implement
USB
2.0 interface for Windows. However, I am facing a problem.

The function usrp_loads_standard_bits() in usrp_prims library loads the
FX2
firmware by calling the following two functions:
get_proto_filename
find_file

In short are we trying to access the std.ihx firmware file by calling
these
two functions? In Windows ofcourse my firmware would not be lying in the
directory specified by std_paths.h (/usr/local/share). Shall I change
the
directory path in std_path.h library, to some path where I have
downloaded
std.ihx myself? Also, I cannot use functions such as access (path, R_OK)
in
Windows, because it is a function of unistd.h which is only available
for
Unix/Linux. How should I go about this problem, so that the firmware can
be
loaded into the FX2 through through Windows platform?

Thanks.
